WILLIAM GOLDING, OF NEW ORLEANS, LOUISIANA.

IMPROVEMENT IN corToN-PRssEs.

Specification forming part of Letters Patent No. l 82,110, dated September 12,1876 'application led July 15, 1876.

To all whom it may concern Be it known that I, WILLIAM GOLDING, of New Orleans, in the parish of Orleans and State ot' Louisiana, haveinvented a certain Improvement in Cotton-Presses, of which the following is a specification:

Mv invention, relating to cotton-presses in which a running wedge is used for adjusting the upper platen with reference to the lower platen, consists of the combination, with such .running wedge, of a hydraulic engine for operating said wedge, the engine being` fed from the boiler which supplies the steam for thev engine actuating the movable lower platen of the press, and having its piston-rod directly` n all the figures in the designation of identical parts.

The drawing shows only that end of the running wedge A to whichf the cross-head C2 ot' the piston-rod G1 is secured or pivoted. rlhe cylinder B of the hydraulic engine is made ofthe proper length and cross-sectional area, to provide for a sufficientlypowerful piston, C, and the required stroke oi the same. The piston-rod is packed by a stufng-box, where it passes through the head of the cylinder. The Water from the boiler D is conducted into the case or chest E, at one end of the cylinder, by a pipe, F, and its How from the chest E is, in this instance, controlled by a four-way cock, Gr, which governs the ports e e e e' ot' the chest.

A passage, H, leads from the port c to one end of the cylinder; an external pipe, I, connects the port e' with the other end of the cylinder; the induction-pipeF covers the port c, and the port e registers with the exhaustpipe K. 4

By a proper manipulation of the four-way cock, the piston may be held steady at any point in the cylinder, or driven in one direction or the other, to run the `wedge in or out, as may be required. 0f course, other known valves, adapted to accomplish the result spoken' the parts, I pivot the cylinder on its support. o

In the examplershown, it is pivoted thus at its extreme end, as at B', the axis of the pivot being parallel to the axis of the cross-head.

To relieve the piston-rod of the weight ot' they cylinder thus pivoted, I employ a counterweight, L1, attached to a rope or chain, L, which is connected to the free end. of the cylder, and reeves over a pulley, L2, as clearly shown in Fig. 1.

It should be understood that the running wedge requires adjustment only when there is any marked difference in the sizes of the bales to be repressed, so that it needs to be moved only periodically. It would, therefore, be rather impracticable to use steam as the motor for actuating the hercinbefore-described engine, because condensation would materially interfere with its practical use in this instance. Besides, the expansive nature of steam renders its use here objectionable, because the movement of the wedge could not be well controlled without providing a more complicated steam-supply valve mechanism. Water, on the other hand, is not liable to the objections against the use of steam for this purpose, and its luse enables me to employ the very simple engine described.

What I claim as my invention, and desire to secure by Letters Patent, is t 1. The combination, substantially as specied, with the running Wedge of' a cotton-press, of a pivoted hydraulic engine, lthe piston-rod of which is directly connected to said Wedge.

2. The combination, substantially as specied, with the running wedge of a cotton-press,
